1 Introduction

There is a wealth of Software-as-a-Service (SaaS) companies today that offer a range of keyword analytics data, such as keyword search volume and keyword difficulty scores. For the end user, it is often challenging to make informed comparisons between different data providers, which may be skewed or misleading when viewed individually.

This large-scale analysis of Keyword Analytics data aims to compare data across various SEO tools. More specificially we will do a comparision of the following variables:

  • Keyword Suggestions
  • Average Monthly Search Volume
  • Keyword Difficulty
  • Cost-per-Click Ads data (in US dollar)

We compare the data of a total of 10 tools:

  • Google Keyword Planner (no Keyword Difficulty output available)
  • Ahrefs
  • SEMrush
  • Moz Pro (no CPC output available)
  • KeywordTool.io
  • KWfinder
  • SECockpit
  • Sistrix
  • LongtailPro (only Volume, Difficulty & CPC)
  • Ubersuggest (only Keyword Suggestions)

1.1 Methodology

  • Step 1 - Collect Seed Keywords: Seed Keywords were sourced from https://www.wordstream.com/popular-keywords. From 15 keyword categories, we selected randomly 5 keywords, totalling 75 keywords.

  • Step 2 - Collect Keyword Suggestion data for each SEO tool: We manually added each of the 75 keywords onto each SEO tool to receive the number of Keyword Suggestions.

  • Step 3 - Input Seed Keywords onto Google Keyword Planner and download all Keyword Suggestions: To gather data on Search Volume, CPC and Keyword Difficulty, we entered 5 keywords from each of the 155 categories onto the GKP. Then, we downloaded all the suggested Keywords into CSV files. This resulted into 59516 keyword observations.

  • Step 4 - Categorise data into different monthly Search Volume buckets and limit observations to 10.000 observations: From the GKP data, we removed search volumes smaller than 100 and dropped all NAs for the relevant variables. As a next step, we categorised the keywords into three search volume keyword size buckets (i.e. 100-1,000, 1,000-10,000, +10,000) and randomly selected 1/3 of observations from each.

  • Step 5 - Upload 10,000 onto each SEO tool and download Average Monthly Search Volume, Keyword Difficulty and CPC Ads data: Lastly, we uploaded the clean GKP data onto each SEO tool and downloaded the results.

1.2 General Notes

  • Multiples could be ordered by ranking of SEO tools (currently as in csv) and/or keyword categories (currently alphabetic) as well.

  • Median values and/or ranking could be replaced by mean. However, we use the median to visualize overall patterns for two reasons: (i) the data is skewed and a median is much less sensitive to skewed data than the average and (ii) the meidan is stable when being transformed to a logarithmic scale while the average is not (and due to the skewed data we need to use a logarithmic scale).



Key takeaways:

  • 11 SEO tools for keyword suggestions with a maximum of 75 keywords.

  • 9 SEO tools for keyword search volume, difficulty scores and CPC with a maximum of 9,909 keywords.

  • Google Keyword Planner does not provide any information on difficulty scores.

  • Moz Pro does not provide any information on CPC.

  • Sistrix has a low number of successful requests with 2,473 (Keyword Search Volume & Keyword Difficulty) and 2,368 (CPC) oberservations out of 10,000.

2 Keyword Suggestions

There are 11 SEO tools, each used to search 75 keywords. The keywords fall into 15 categories with each category containing 6 keywords. Minimum of suggestions was 5 and the highest value was 6,588,805.

2.1 Keyword Suggestions per SEO Tool

Key takeaways:

  • Ahrefs (43,488 and 23,021) and SEMrush (36,523 and 25,475) generate the most overall keyword suggestions, Google Keyword Planner (691), and KWfinder (581) the least.

  • The Google Keyword Planner provides 67.9% fewer keyword suggestions compared to (the median of the) other major paid SEO tools.

  • When we pit the Google Keyword Planner against the top tools in terms of keyword suggestions, we found that the Google Keyword Planner generates 98.1% fewer suggestions than SEMrush, 97% fewer than those made by Ahrefs, and 83.8% fewer than by Ubersuggest.

  • In general, we found a wide range of keyword volumes for the same exact set of keywords. For example, take a keyword like “insurance”. According to Google Keyword Planner, that keyword gets 789 searches per month. However, if you look up that same keyword in Ahrefs, you’ll get a completely different number of 6.59 million suggestions!

  • KWfinder, Google Keyword Planner, and KeywordTool.io reach very low levels of suggestions with a median below 1,000.

  • Moz Pro returns always a maximum of sugestions given the limit that is imposed by the software.

  • KWfinder never generates 1,000 suggestions or more.

Summary Plot

Each Search (The Raw Data)

To see more of the underlying pattern in keyword suggestions, we transform the x axis to a logarithmic scale and use so-called beeswarm plots to make the distribution more clear to the reader.

Takeaways:

  • Plot highlights how skewed the data is in terms of keyword categories and SEO tools (with a focus on categories).

  • Due to the skewed data, a logarithmic scale helps to visualize the large range of keyword suggestions.

Distributions & Ranges

Distributions can be effectively summarized as box and whiskers plots which indicate the median (thick line), the interquartile range (box), the minimum and maximum excluding outliers (whiskers), and outliers (points):

The pattern might be easier to read as linerange plot by showing the minimum-maximum range (line) and the median (dot):


Takeaways:

  • Patterns among Ahrefs, SEMrush, Sistrix, and Ubersuggest are more or less the same.

  • Google Keyword Planner, Moz Pro, SECockpit, KeywordTool.io, and KWfinder generate considerably less suggestions for most keyword categories.

  • KWfinder and KeywordTool.io show almost no variation (standard deviation of 98 and 335, respectively).

  • Moz Pro has no variation among keyword categories nor within each category (retunrs always 1,000 suggestions standard deviation of 0).

  • Interestingly, Financial Services does not score the most suggestions with Google Keyword Planner; Women Fashion and Diet have remarkably higher median values when compared to the other cateories (partly true for SECockpit as well).

2.2 Keyword Suggestions per Keyword Category

Key takeaways:

  • Financial Services (9,373), Online Marketing (6,128), and Women Fashion (3,661) generate the most suggestions, followed by Home Improvement (3,241), Wedding (2,373), Diet (2,168), and Gardening (1,754) when ranked by overall median.

  • Office Supplies (825), Web Hosting (1,000), and Dating (1,000) generate the least suggestions when ranked by overall median.

Summary Plot

We use the median to visualize overall patterns for two reasons: (i) the data is skewed and a median is much less sensitive to skewed data than the average and (ii) the meidan is stable when being transformed to a logarithmic scale while the average is not (and due to the skewed data we need to use a logarithmic scale later).

Each Search (The Raw Data)

Takeaways:

  • Plot highlights how skewed the data is in terms of keyword categories and SEO tools (with a focus on categories); the large grey dot indicates the median per category.

  • Due to the skewed data, a logarithmic scale helps to visualize the large range of keyword suggestions.

  • The distinct number of 1,000 suggestion deliverd by Moz Pro is clearly visible with a turquoise dotted line at that value.

Distributions & Ranges

Takeaways:

  • Ahrefs and SEMrush are more competitive in the categories Home Improvement, Online Marketing, Women Fashion, Legal, Automotive, Solar Energy, Vacations Travel, and Wedding when compared to the other SEO tools.

  • Ahrefs suggest notably more keywords in the categories Office Supplies, Vacations Travel, and Web Hosting

  • Google Keyword Planner and Moz Pro reach comparable amounts of suggestions as the other tools only in the categories Web Hosting and Office Supplies.



2.3 Keywords per Engine & Category

In the following, we investigate the data in a more detailled manner: each keyword, encoded by SEO tool and keyword category.

Key takeaways:

  • No clear pattern of one keyword category dominating the top keywords.

  • Top 10 keywords belong to a variety of categories: Financial Services, Women Fashion (both with 3 out of 10), Online Marketing, Home Improvement Diet, and Automotive (each 1 out of 10).

  • Ahrefs and SEMrush have notably higher amounts of suggestions for most keywords when compared to the other three SEO tools (often 5 to 8 times more than Ubersuggest which is ranked 3rd).

Linear Scale

Logarithmic Scale

All 75 Keywords on a Logarithmic Scale

Takeaways:

  • Plot highlights the bias in keyword suggestions with a few keywords gaining high numbers; while this shows how skewed the data is, it makes it difficult to compare the amount of suggestions among SEO tools within a particular keyword.

  • A visualization using a logarithmic scale for keyword suggestions might help here:

Top 25 Keywords on a Logarithmic Scale

Takeaways:

  • It is immediately apparent that Ahrefs and SEMrush have by far the most suggestions in comparison to Ubersuggest, Sistrix, SECockpit, Moz Pro, KeywordTool.io, Google Keyword Planner, and KWfinder.

  • However, the skewed distribution among keywords within SEO tools is masked.


3 Keyword Search Volume

Key takeaways:

  • Ahrefs and KWfinder generate always less search volume than Google Keyword Planner (a maximum difference of -2,200 and -1,900 in volume category 10,000+, by far the lowest values in this volume category).

  • Most top keywords with regard to search volume are requests related to financial services.

  • In general, all 9 SEO tools show a siginificant negative correlation of search volume and keyword lenght: the more characters the lower the search volume (volume = 10^(4.3739 + (-0.049) * length)). For example, using Google Keyword Planner, searching for a keyword with 20 characters reduces the search volume by 5,177 in comparison to a search with 10 characters.
